comes from the java.lang.Comparable interface, implemented to compare this object with another to give a negative int value for this object being less than, 0 for equals, or positive value for greater than the other. This is the more convenient compare method, but must be implemented in ever...
Any interface can be functional interface, not merely those that come with Java. To declare your intention that an interface is functional, use the@FunctionalInterfaceannotation. Although not necessary, it will cause a compilation error if your interface does not satisfy the requirements (ie. one ...
方法引用的等效lambda表达式 String::compareToIgnoreCase 将具有形式参数列表(String a, String b),其中a和b是用于更好地描述此示例的任意名称。方法引用将调用该方法 a.compareToIgnoreCase(b)。我反正是没看懂这是讲的啥。之后再查了下,原文是这样的 “reference to an instance method of an arbitrary object ...

You can either use the compareTo method implementation of the associated entity class or a custom Comparator to sort the entities. Now, let’s take a look at ordering. Ordering The ordering feature is defined by the JPA specification and does what most developers expect. It uses an ORDER BY...
because Perl provides a standard class to do this for you:Unicode::Collate. Don’t let the name throw you, because while it was first invented for Unicode, it works great on regular ASCII text, too, and does a better job at making lexicographers happy than a plain oldsortever manages....
